The Effects of Geological Formations on Quality Groundwater with Application Boolean Logic (Case study: Emamzadeh Jafar plain)

In this study, the quality of groundwater resources and their correlation with geology formation was considered. For this purpose, using the geological map of the area and geological formation were extracted. Then the qualitative data of 40 operation well and piezometer, to determine the water brigade was entered to the software chemistry. The following formations according to the type of production and the effects of quality, were classified; In the next step, buffers in intervals of 1, 3, 5, 7 and 10 kilometers was created around wells and layers were cut with geological maps. The results obtained using the t-test showed that at 95%, at 1, 3, 5 and 7 kilometers of wells, The impact dissolution of formation on operation wells, is significant but at a distance of 10 kilometers and with increasing distance, this effect was less and significant effect there is not in this respect, But their total impact of non-Quaternary on the wells increases. The results of the Boolean logic also showed that the Qt2 Formation has the most expansion in the proximity of wells, including alluvial fans and young alluvial sediments and are the main aquifer feeding site. But as the distance from the wells increases, the impact of non-Quaternary formations, such as Asmari Lime and the Gachsaran Group Formations, which have the potential to produce carbonate and chlorite types, increases.
